    • A nozzle segment (451) for a turbine nozzle (450) of a gas turbine engine (100) is disclosed. The nozzle segment (451) includes an upper endwall (453), a lower endwall (463) spaced apart from the upper endwall (453), a pressure portion (470), and a suction portion (480). The pressure portion (470) extends between the upper endwall (453) and the lower endwall (463) adjacent a first side (460) of the nozzle segment (451). The suction portion (480) is spaced apart from the pressure portion (470) and extends between the upper endwall (453) and the lower endwall (463) adjacent a second side (461) of the nozzle segment (451). The second side (461) is opposite the first side (460).
